Abstract

A presente invenção previne a redução de segurança e refere-se a aparelho de refrigeração para executar ciclo de refrigeração em circuito refrigerante (RC) de sistema de ar condicionado (100), o dispositivo de refrigeração com trocadores de calor externo (20) e interno (32), primeira (41), segunda (42) e terceira válvulas de controle (43) e unidade de ajuste de pressão (44). A primeira (41) e a segunda (42) bloqueiam o fluxo de fluido refrigerante quando estão completamente fechadas e dispostas em caminho de fluxo de fluido refrigerante do lado do gás (GL). Este caminho (GL) entre os trocadores de calor externo (20) e interno (32). A terceira (43) bloqueia o fluxo de fluido refrigerante quando está completamente fechada e disposta em caminho de fluxo de fluido refrigerante do lado do líquido (LL). Este caminho (LL) entre os trocadores de calor externo (20) e interno (32). Unidade de ajuste de pressão (44) ajusta a pressão do fluido refrigerante em caminho de fluxo de fluido refrigerante do lado interno (IL). Este caminho (IL) entre as primeira (41) e segunda válvulas (42), ou entre a terceira (43) e o trocador (32). A unidade de ajuste de pressão (44) inclui válvula de ajuste de pressão (45). Esta (45) desvia o fluido refrigerante presente no caminho de fluxo de fluido refrigerante do lado interno (IL) para caminho do lado externo (OL). Este caminho (OL) entre as primeira (41) e segunda válvulas (42), ou entre a terceira válvula (43) e o trocador (20).The present invention prevents the reduction of safety and relates to a refrigeration device to perform a refrigeration cycle in a refrigerant circuit (RC) of an air conditioning system (100), the refrigeration device with external (20) and internal heat exchangers (32), first (41), second (42) and third control valves (43) and pressure adjustment unit (44). The first (41) and the second (42) block the flow of refrigerant fluid when they are completely closed and arranged in the refrigerant fluid flow path on the gas side (GL). This path (GL) between the external (20) and internal (32) heat exchangers. The third (43) blocks the flow of refrigerant when it is completely closed and disposed in the liquid side refrigerant flow path (LL). This path (LL) between the external (20) and internal (32) heat exchangers. Pressure adjusting unit (44) adjusts the refrigerant pressure in the inner side (IL) refrigerant flow path. This path (IL) between the first (41) and second valves (42), or between the third (43) and the exchanger (32). Pressure adjustment unit (44) includes pressure adjustment valve (45). This (45) diverts the coolant present in the coolant flow path from the inner side (IL) to the outer side path (OL). This path (OL) between the first (41) and second valves (42), or between the third valve (43) and the exchanger (20).
